Assessment of associative relations in alzheimer's disease: Evidence for preservation of semantic memory

Abstract

Semantic priming was assessed in Alzheimer's disease (AD), elderly control, and young control subjects with three lexical decision, continuous priming experiments. the stimuli were intracategory, associated pairs in Experiments 1 and 2 and varied types of associated pairs in Experiment 3. AD priming effects were equal to those of elderly control subjects; elderly and young control priming effects were also equal. We interpret this as evidence for the relative preservation of the semantic memory network in early AD, as in normal aging, at least to the extent necessary for normal access of concept nodes and normal automatic spreading activation between concept nodes. In a final study (Experiment 4) knowledge of the associations between the targets and related primes used in Experiments 1 and 2 was explicitly assessed; 20 out of 22 AD subjects showed perfect or close to perfect performance.     

Dyadic Models for the Study of Health

Dyadic designs have been used in health research to investigate intra‐ and inter‐personal mechanisms of health and well‐being in various types of dyads, including parent–child dyads, siblings, friends, and romantic partners. Although a growing number of researchers are designing studies that capture the interdependent complexities of relationships, many still need more information on how to analyze the data in a way that maximizes its value. Therefore, the purpose of this review paper is twofold: (1) to address some of the ways in which dyadic data analysis is being used in current health research, with an emphasis on research that has employed the Actor‐Partner Interdependence Model, and (2) to propose and explain various methodological and substantive considerations that researchers should consider when using dyadic data analysis in their own research.     

Review of The Supervisor's Guidebook: Evidence-Based Strategies for Promoting Work Quality and Enjoyment Among Human Service Staff (2nd edition) by Dennis Reid,Marsha Parsons,and Carolyn Green

This article summarizes a review of the book The Supervisor's Guidebook: Evidence-Based Strategies for Promoting Work Quality and Enjoyment Among Human Service Staff (2nd edition) by Reid, Parsons, and Green. We describe the book's organization and content. In addition, strengths and areas for improvement are noted. The book provides rich, relevant content to guide supervisory practices within a participative, evidence-based approach that could be applied in various human service settings.     

Rodney King and O. J. Revisited: The Impact of Race and Defendant Empathy Induction on Judicial Decisions

White university students participated in a study to investigate the impact of defendant race and empathetic induction on a subsequent juror decision-making task. Participants read a passage involving a Black or a White defendant in a criminal case. They were subsequently induced to feel no empathy, low empathy, or high empathy for the defendant. When compared to participants in the low- and control empathy conditions, those in the high-empathy condition reported greater target empathy, made attributions that were more situational, and assigned more lenient punishments. The results also indicate that group membership can moderate the impact of empathetic induction. When compared to the participants in the Black defendant condition, those in the White defendant condition reported greater target empathy, made attributions that were more situational, and assigned more lenient punishments. Implications for both empathy and judicial decision-making research are discussed.     

Sweetening the Till: The Use of Candy to Increase Restaurant Tipping1

A common practice among servers in restaurants is to give their dining parties an unexpected gift in the form of candy when delivering the check. Two experiments were conducted to evaluate the impact of this gesture on the tip percentages received by servers. Experiment 1 found that customers who received a small piece of chocolate along with the check tipped more than did customers who received no candy. Experiment 2 found that tips varied with the amount of the candy given to the customers as well as with the manner in which it was offered. It is argued that reciprocity is a stronger explanation for these findings than either impression management or the good mood effect.     

The Role of Attachment Styles and Interpersonal Problems in Suicide‐Related Behaviors

The relationships among adult attachment styles, interpersonal problems, and categories of suicide‐related behaviors (i.e., self‐harm, suicide attempts, and their co‐occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide‐related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.     

Self-Affirmation Reduces Biased Processing of Health-Risk Information

An experiment tested whether a positive experience (the endorsement and recall of one's past acts of kindness) would reduce biased processing of self-relevant health-risk information. Women college students (N = 66) who reported high or low levels of daily caffeine use were exposed to both risk-confirming and risk-disconfirming information about the link between caffeine consumption and fibrocystic breast disease (FBD). Participants were randomly assigned to complete an affirmation of their kindness via questionnaire or to a no-affirmation condition. Results indicated that the affirmation manipulation made frequent caffeine drinkers more open, less biased processors of risk-related information. Relative to frequent caffeine drinkers who did not affirm their kindness, frequent caffeine drinkers in the affirmation condition oriented more quickly to the risk-confirming information, rated the risk-confirming information as more convincing than the risk-disconfirming information, and recalled less risk-disconfirming information at a 1-week follow-up. They also reported greater perceived personal control over reducing their level of caffeine consumption. Although frequent caffeine drinkers in the affirmation condition initially reported lower intentions to reduce their caffeine consumption, there was no evidence that they were less likely to decrease their caffeine consumption at the follow-up. The possibility that positive beliefs and experiences function as self-regulatory resources among people confronting threats to health and well-being is discussed.
